The number two seed from New York, who was champion between 2009-11, went into the match as the firm favorite having qualified from his group with ease, and the Floridian scraping through his group by the narrowest of margins.

However the match, which was played at a methodical pace, went right down to the wire with Deuel eventually wrapping up the tie on the final blue ball for a surprise victory, and he will now face local debutant player Andy Jewthra in the quarterfinals who scored a 3-0 win over New York's Kevin Wong.

Apart from Deuel's match, the remaining quarterfinals were completed in a brisk pace with the defending champion and number one seed Sargon Isaac brushing aside Omar Moton 3-0, and he will play in the next round the terrific grand man of United States snooker, Tom Kollins, who at the age of 77, has reached yet another quarterfinal by defeating New York's Lap Mui, 3-0.

There will be a mouthwaterting quarterfinal between the number four seed, Romil Azemat, and local debutant player Mark White, who came through their respective Round of 16 matches against Mohammed Ajmal and Cheang Ciing Yoo. Both players have been very impressive throughout their matches and a high-quality tie between these two players is expected.

Another quarterfinal expected to thrill will be between the number three seed and former champion, Ajeya Prabhakar, and New York's former runner-up and number six seed, Raymond Fung. Both players came through the Round of 16 with victories over Henry Wong, a semifinalist back in 2011, and Vaishal Talati respectively, and have played excellent snooker throughout, particularly Prabhakar who holds the tournament's highest break so far of 76.
